April 29, 2026 | An international research team led by JGU has analysed genomes from the period around the end of the Western Roman Empire. The study provides new insights into a time of profound change in Central Europe and has been published in the journal Nature

Many of today’s villages and towns in Central Europe trace their origins to settlements that emerged after the collapse of the Western Roman Empire, often on former Roman territory or in the immediate vicinity of the Limes, the former imperial frontier. Since the nineteenth century this period was often associated with the idea of large migrating groups of Germanic peoples. However, historical research has long since moved away from the concept of a unified Germanic identity and large-scale migration events. An international research team led by anthropologist and population geneticist Professor Dr. Joachim Burger from the Institute of Organismic and Molecular Evolution at Johannes Gutenberg University Mainz (JGU) has now analysed genomes of individuals from the former Roman frontier zone between 400 and 700 AD in southern Germany. Their results provide unexpectedly detailed insights into a period of major transformation. The findings have been published in the journal Nature.

The interdisciplinary study involved around sixty researchers from a range of European institutions, including JGU, the University of Tübingen, the University of Fribourg in Switzerland, the University of Freiburg in Germany, the Bavarian State Collections of Natural History, and several other institutions. The researchers come from fields such as population genetics, bioinformatics, anthropology, history and archaeology. The study focused on genomes from skeletal remains found in so called row grave cemeteries, burial sites that became widespread from the mid fifth century across northern Gaul, western and southern Germany, and as far as Hungary.
